OpenGL version under Lubuntu 18.04(3.3) is lower then on Windows(4.1)

Question

I'm posting today about an odd occurrence I've run into. So I have a machine that was running Windows 7 and I switched it over Lubuntu 18.04LTS. I've updated to the latest(? Apparently not... maybe for my GPU?) via ppa:oibaf/graphics-drivers. Yet my OpenGL version reads 3.3 instead of the 4.1 I get on windows. From the glxinfo command it seems I don't have the newest version of mesa(19.0.2) while kisak's ppa for example shows 19.3.2 and oibaf shows some hash(as of writing).

I've tried this on Ubuntu 18.04LTS live disc but the output of glxinfo was identical and displayed OpenGL 3.3. amdgpu-pro failed to install due to deps issue.

Speccy read out of GPU openGL version(4.1) image

EDIT: After posting this and continuing to google around, I came across this: OpenGL Max core profile stuck at 3.3 which links to https://www.x.org/wiki/RadeonFeature/#note_19 which reads "OpenGL 4.2 is currently only supported on CYPRESS, CAYMAN and ARUBA. All other chips are currently limited to OpenGL 3.3"... I have a JUNIPER... anything change in the 3 or so years? :p Could I achive it any other way... maybe through a VM or something with gpu passthrough(?)... I haven't looked much into it.
